with constancy of resilient between thrusts and reactions' and with definite rangescf resilient movements preferably of approximately three-eighths of an inch on the vertical line of thrust with or without means to vary the internal resilient resistance balance, and capacities of the annular body.

. My present invention maybe em loyed in conjunction with any desired resi ient tire construction, having is especially designed to be employed, with transversely elongated constructions provided in the outer part with one or more tensile belts havin a tensile capacity largely in excess of 10a and provided with an inner cushioning belt wh ch provides for a predetermined range of resilient altitude under a determined load. The construction of the cushioning belt may provide for the use of fluid or compressible content, which will provide resilienc in the entire annular portion and not local as in the ordinary types of pneumatic, cel ular or solid tire constructions. The wheel e ui ment, asherein defined, provides normally a constant capacity to support a predetermined load due to the fact that the side walls of the construction have constant support through this medium of the sides of the cushioning With the above and-other objectsin view, which will more clearly hereinafter appear in the detail description, my invention consists of a novel resilient wheel equipment, which is adapted to be employed in conjunction with solid, cellular, or resilient tire construction. o

It further consists of other novel features of construction, all as will be hereinafter fully set forth.

Referring to the drawings:

In a copendin applicatlon, I have described and broa ly claimed a novel construction of resilient wheel equipment,

wherein an annulus 1s secured in compressive engagement with the compressible terminals of a resilient tire construction, such terminals being thereby rendered circumferentially inextensible.

In my present invention instead of em ploying a single annulus, I rovide an annulus In conjunction with w ich I employ clamping or looking rings which serve to lock the terminals of the tire in compres- 'sive 'engagementwith the annulus.

Referring first to Figs. lto 10 inclusive, 1 designates a felly to which is secured, in 'any desired or conventional manner, a band 2, which has welded, riveted or otherwise secured thereto a locking'lug 3. The band 2 is preferably 'formed by a rolling process, and the lug 3 secured thereto in the manner described.

4 designates an annulus, which is also adapted to be formed by a rolling process,

and has near each side on its inner face, the inwardly extending flanges 5, which form a central annular channel 6. In order to form means to interlock with the lug 3 of the or otherwise secure to the annulus 4, the lugs. 7 and 8 W11 V y ich are preferably located infthe channel 6. The

-annulus 4 is transversely divided as indicated at 9, and I weld, rivet or otherwise secure to one end of the annulus a plate 10, having an overlappin portion 11 which, extends into the charms as indicated at 12,

indicated at 13, to form at each side an inner shoulder 14, which serves to retain in position rings 15, which 'have an angular contour, it being noted that these rings may be inserted, as in Fig. 8, with the base flange 16 extending outwardly or as in with the base depending upon the construction of the tire construction in conjunction with which they are employed.

6, on the other end of the annulus 4." The outer face of the annuice 4 extends laterally and at the sides is outwardly deflected, as

In pre etioe, I preferably provide the felly hand 2 with an outwardly extending flange 41 which serves to aline the annulus 4 with respect to the telly, and as a positive abutment to prevent relative lateral movement of the annulus with respect to the telly band, litbeing understood-that movement in the other direction is prevented i y means of the clip 89. TheheadBS of the holt 37 is preferably 013:- set in order-to extend over the side of the Referring now to the embodiments seen in Figs. 11 and 12, the construction of the telly band 2, the annulus 4, and the locking rings is similar to that already described with reference to other figures of the drawing-end 1 have therefore "vensueh parts the same referenoenumerals. Ihe flocking rings in Figs. -11 and 12 act as cleneherrings.

In this embodiment, I have shown a type of resilient eonstruotion wherein is employed within the tensile belt 42 a cushion insert 4%, whieh is removable if desiredend the inner feoeef this insert is curved as at 44;, 'for-m with the inner face of a layer of filling 45 a spaveement 4: 6, whieh may "be sues with fluid under pressure through the valve 47 which corresponds in oonstruetion tothut seen in Figsp8 and 9,h-ut Whioh is secured with respeetto the annulus j'in a d-ilferent manner. The layer of fi'llialgliiis cellular, as indicated at 48, and the inner face thereof is curved, as indicated, at 49, and formed by a layer of fabric and rub her. The terminals 50, of the resilient tire construction are oompressive engagement with the oleneherrings lfi and the annulus '4, it *beingunderstood-that the fil l ingrfi permits the necessary inward movement of the'tennina ls to permit a elenc'her ring 15 239 foreed'into engagement with the inner "e of the eu'twerdly extending fienge '18 ofthe annulus 4, in order to loeksudh terminals in compressive engagement withsuch annulus a y y i a The annulus 4, if desired, may be provided with an annular. groove 51,,see Figs. 8 and 10, adapted to receive the clips 39, but in many cases arising in practice the provision of such groove is unnecessary and can be readily dispensed with.

When it isdesirecl to demount the rim or remove the wheel equipmenhit :is simply necessary to removethe nuts 40 whereupon the clips 39 may be readily removed andthe annulus 4 and its adjuncts may be readily removedr l a Incases wherein it is simply desirous to remove the resilient tire construction, it is simply necessary to move a locking ring 15 laterally and then outwardly so as to release the same from its engagement with the flan e 13 of the annulus iywhereupon the termina s of the tire will be released and the same can be readily removed. lhe insert located between the terminals may form apart of the cushionbelt, as seenin Fig. 10, or the same, ifdesired, may be formed of a separate fillinglayer as will be understood by reference to Figs. 11 and 12. 4

While in practice I preferably employ an outwardly'extending flange on thefelly band 2, to positively limit the lateral movement in one directionof the annulus 4, it will be apparent that such flange in many cases arising in practice is unnecessary and may be dispensed with and still be ,within the broad and generic scope of my invention.

The cushionin field 43 consists of a de sired numberv of ayers 52 which are formed of fabric of a comparatively loose weave,

through the pores of which rubber 53 extends, it being understood that the sides of each layer of fabric are faced with a layer of rubber 54:, of any desired thickness, in orderto provide the proper amount of friction material between the difierent layers of fabric. The rubber extending through the pores of the fia'bric forms anelastic bond between the respective layers 0t .rubberaand fabric, ,andrenders the construction practically impermeable .to moisture; as: well'as resistantgto fluid pressure.v ,v r J It is: designed to require a considerable amountof pressure upon the sides ofthe annularbody and otherwise on the rings in placing the annulus on the rings whereby the terminalsare securely fixed and relatively immovable therewith when so secured, the resilient cushion being-thereby brought into thewdesired retroactively resilient engagement and support withthe tension memberthroughout thelengtlrs of the curvatures of;one;hun dred an eighty degrees or more at the sides and to any further extent desired across the outer or inner or both outer and inner transverseportions or with the slight? curvatures in such portions relatively thereto between such curvatures at the sides. a s

It is furthermore designed that theterminalsand outer seating parts inwardly of the resilient cushion shall be made circumferentially inextensible and firmly secured compressively against such inextensible seatin parts by the transversely divided annu us. a v

It will. now be apparent that I have devised a noveland useful construction of a resilient" wheel equipment which embodies the features of advantage enumerated as desirablein the statement of the invention and the a'bove description and while I have, in the present instance shown' and described preferred embodiments thereof which will give in practice satisfactor and reliable results, it is to be understoo that the same aresusceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.
